Atrial fibrillation after surgery for esophageal carcinoma： Clinical and prognostic significance

AIM： To retrospectively evaluate the clinical relevance, perioperative risk factors, outcome of different pharmacological prophylaxis, and short-term prognostic value of atrial fibrillation （AF） after surgery for esophageal carcinoma. METHODS： We retrospectively studied 63 patients with AF after surgery for esophageal carcinoma in comparison with 126 patients without AF after esophagectomy during the same time. Postoperative AF incidence was related to different clinical factors possibly involved in its occurrence and short-term survival. RESULTS： A strong relationship was observed between AF and postoperative hypoxia, history of chronic obstructive pulmonary disease （COPD）, postoperative thoracic-gastric dilatation, age older than 65 years, male sex and history of cardiac disease. No difference was observed between the two groups with regard to shortterm mortality and length of hospital stay. CONCLUSIONS： AF occurs more frequently after esophagectomy in aged and male patients. Other factors contributing to postoperative AF are history of COPD and cardiac disease, postoperative hypoxia and thoracicgastric dilatation.
